CLOSURE DEVICE Filed Feb. 5, 1940 Vinceni F! Palmer ATTORNEYS PatentedFeb. 24, 1942 UNITED STATES PATENT QFFICE 3 Claims.

My invention relates to closure devices for containers and has as one ofthe principal objects thereof the provision of a closure device which issimple in construction, durable in use, efficient in operation andeconomical in manufacture.

Another object of my invention is to provide a closure device of theabove described character so constructed andarranged whereby the samemay be readily attached to containers and equipped with means foreffecting efficient and convenient delivery or discharge of the contentsof a container, such for example as the exuding paste from collapsibletubes and the discharge of pills from bottles or the like.

Other objects and advantages will be apparent from the followingdescription, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designatelike parts throughout the several views:

Figure 1 is a side elevation of my invention,

illustrating the same as applied to the discharge end of a collapsibletube.

Figure 2 is a vertical sectional view of my invention as applied to thetube.

Figure 3 is a top plan view thereof.

Figure 4 is a perspective View of the closure device with the slideremoved.

Figure 5 is a perspective view of the slide.

In practicing my invention I provide a closure device 5 having a head 6fashioned with a subjacent shank I, the latter having an interiorlythreaded bore 8 threadedly connected to the threaded discharge end 9 ofa collapsible tube Ill. The bore 8 has communicating therewith adischarge opening II through which the contents of the tube II] aredischarged as hereinafter set forth and with the discharge opening of alike diameter as the bore of the discharge end 9 of said tube.

The head 6 of the device comprises a pair of spaced side sections I2having oppositely disposed faces 13 formed with longitudinally extendinggrooves M slidably receiving therein V-shaped ribs I5 fashioned on theside faces I6 of a slide II interposed between the sections I2. Thebottom face of the slide I1 normally closes the upper end of the openingII and precludes discharge of any of the contents of the tubetherethrough. The grooves I4 are fully open at their ends to permitremoval of the slide from the head.

The end faces of the slide have extending therein angled ends of a bailor spring lock I8,

' the latter being of a substantially U-shaped configuration andpreferably constructed of spring wire. The sides of thebail I8 adjacentthe ends thereof are provided with angled sections I9 Which seat betweenspaced pairs of projections 20 formed on the outer faces of each of thesections I2 whereby to secure the slide I! in locked condition withrespect to the sections I2 to preclude accidental opening of thedischarge opening II when thetube is not in use. Obviously, by disposingthe bail I8 upwardly over the slide II, the latter may be actuated toopen position or entirely detached from the head 6.

Without further elaboration, the foregoing will so fully explain theinvention that others may,

by applying current knowledge, readily adapt the samefor use undervarious conditions of service. Moreover, it is not indispensable thatall the features of the invention be used conjointly since they may beemployed advantageously in various combinations and sub-combinations.

It is obvious that the invention is not confined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable. It is therefore to be understood that the invention is notlimited to the specific construction as illustrated and described, asthe same is only illustrative of the principles of operation, which arecapable of extended application in various forms, and that the inventioncomprehends all construction within the scope of the appended claims.

I What I claim is: I

1. In a closure device having a slotted head and a slide member slidablyfitted in the said slot, a bail pivotally connected with the ends of theslide operable to embrace part of the head to releasably lock the slidein the slot.

2. In a closure device having a slotted head and a slide member slidablyfitted in the said slot, 9. member pivotally connected to the slidemovable, when the slide is in closed position, to embrace a side sectionof the head.

3. In a closure device, a head having a pair of spaced apartcomplementary sections, a slide member mounted to slide between the saidhead sections, and a locking member of approximate arcuate contourhaving its ends pivotally connected to the slide member operable toembrace one of the head sections to releasedly lock the slide in closureposition.
